@James500, can you either add a sourced mention of the demo to either page, or show me how you're accessing the reference so I can add it myself? czar⨹ 11:06, 2 May 2015 (UTC)

The snippet produced at the moment by Google Books is this. The immediate context of this particular extract is discussion of a group of people calling themselves "Freezers" who made the demo called "Lech". I am afraid that I can't show you how I originally accessed this source because, at the time, Google Books was using plain text snippets, whereas they have now reverted to using snippets that depict part of a scanned image, which unfortunately often show considerably less content. If you need to see more of the book, I am afraid you will have to obtain a copy, perhaps from a library. James500 (talk) 11:15, 3 May 2015 (UTC)
